The reactions of two nucleophilic palladium carbene complexes with the strong Lewis acid B(C6F5)3 afforded two zwitterionic products. One of them features a remote nucleophilic attack at the para-carb...

The bond activation chemistry of B(C6F5)3 and related electron-deficient boranes is currently experiencing a renaissance due to the fascinating development of frustrated Lewis pairs (FLPs). B(C6F5)3's...

The primary objective of this study is to demonstrate the efficacy and safety of the carbon
dioxide for subcutaneous fat reduction.

Medical and Biotech [MESH] Definitions

Phosphoenolpyruvate Carboxylase

An enzyme with high affinity for carbon dioxide. It catalyzes irreversibly the formation of oxaloacetate from phosphoenolpyruvate and carbon dioxide. This fixation of carbon dioxide in several bacteria and some plants is the first step in the biosynthesis of glucose. EC 4.1.1.31.

Lewis Acids

Any chemical species which accepts an electron-pair from a LEWIS BASE in a chemical bonding reaction.

Lewis Bases

Any chemical species which acts as an electron-pair donor in a chemical bonding reaction with a LEWIS ACID.

Carbonic Anhydrases

A family of zinc-containing enzymes that catalyze the reversible hydration of carbon dioxide. They play an important role in the transport of CARBON DIOXIDE from the tissues to the LUNG. EC 4.2.1.1.

Boranes

The collective name for the boron hydrides, which are analogous to the alkanes and silanes. Numerous boranes are known. Some have high calorific values and are used in high-energy fuels. (From Grant & Hackh's Chemical Dictionary, 5th ed)
